Event capturing in Mithril.js

mithril.capturingEventHandler.js

// Event capturing for Mithril.js
// Demo here: http://jsfiddle.net/barney/vsw8r3Lh/
m.capture = function capturingEventHandler( eventName, handler ){
	function bindCapturingHandler( element ){
		element.addEventListener( eventName, handler, true );
	}

	return function config( element, init ){
		if( !init ) bindCapturingHandler( element );
	};
};

Cool. You should add a context.onunload to the config function to prevent event leakage.

something wrong with the jsfiddle
